PADLOCK.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed December 26, 1914. Serial No. 879,151.

To all whom it may concern:

Be it known that I, MARTIN YAKUS, a subject of the Emperor of Austria-Hungary, residing at South Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates to new and useful improvements in padlocks.

The primary object of the invention is to provide a keyless padlock readily operable for locking or releasing the shackle at will by a definite required shifting of the locked parts which are familiar to an authorized person but which would be exceedingly difiicult of operation by any one unfamiliar with the lock.

A further object is to provide a padlock having a bodily movable shackle adapted for releasing by a spring pressed pin upon position an exterior swinging lever in a predetermined position while the shackle is readily relocked automatically upon being reinserted in the lock casing.

A still further object is to provide a padlock of the keyless variety consisting. of but few parts and being easy and cheap to manufacture and which embodies with a bodily removable lockable shackle, a manually operable closure for the shackle which can only be manipulated when the shackle is unlocked and removed from its casing.

With these general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views :Figure 1 is a front elevation of the device in its locked position. Fig. 2 is a side elevation thereof and with the operating lever illustrated by dotted lines in its releasing position. Fig. 3 is a rear elevation of the device. Fig. A is a view similar to Fig. 1 but with the casing shown in central longitudinal section. Fig. 5 is a central longitudinal sectional view through the device taken upon the plane of the locking pin. Fig. 6 is a transverse sectional view taken upon line VIVI of Fig. 5, the locking pin being in its projected locked position but the shackle being'removed. Fig. 7 is a view similar to Fig. 6 but with the locking pin released. Fig. 8 is a perspective View of the entire mechanism withdrawn from the locked casing. Fig. 9 is a perspective view of the locking post. Fig. 10 is a perspective view of the locked casing. Fig. 11 is a perspective view of the shackle removed. Fig. 12 is a view similar to Fig. 9 but taken from the opposite side of the post. Fig. 13 is a perspective view of the operating lever detached. Fig. 1 1 is a perspective view of the shackle retaining nut employed with the locking post, and Figs. 15, 16 and 17 are enlarged perspective views of the locking pin and its projection spring and slide plate respectively separated from each other.

In this form of padlock, a cup form of locked casing 10 is provided having a neck 11 provided with one flat side 12 and with oppositely positioned alining longitudinal slots 13 adapted for the reception of a removable shackle 14. A locking post 15 of the form best illustrated in Figs. 9 and 12 is provided for closing the shackle as well as locking the same with its ends received in the neck of the casing and the said locking post consists of a head or block 16 and a threaded shank 17.

The shackle is in the form of an interrupted annulus and-has its opposing ends 18 provided with inwardly extending hooks 19 which are adapted to be received within opposite notches 20 in the bottom of the post head 16 while a locking nut 21 having wrench-hold Surfaces- 11 is adapted to be screwed upon the post shank 17 for retaining the shackle hooks in engagement with the post head. It will be noted that the said shank is provided with a longitudinal slot 22 while the end of the nut is tapered as at 23 for engaging the beveled end 24L of one of the bifurcations of the shank which presses such bifurcated portion inwardly upon securing the nut upon the shank and thereby serving as a nut lock for the device. One side of the shank is cut off as at 25 leaving that side thereof of less length than the side of the shank at the opposite side of the slot 22.

The post head 16 is adapted to be readily inserted in the casing neck 11 and has one flattened side 26 corresponding with the side 12 of the neck while the head has a trans-v verse bore 27 therethrough which is positioned in alinement with a perforation 28 of the neck side 12 when the locking post is positioned within the locking casing. An operating lever 29 is provided with an angularly extending tubular arm 30 rotatively positioned within a longitudinalside opening 31 of the post head and which opening extends transversely of the said bore 27. The free end of the arm 30 is slitted as at 32 and is riveted over against the lower face of the post head for retaining the lever arm within the said opening 31. A locking pin is slidably positioned within the bore 27 and has a reduced shaft 3i upon which a slide plate 35 is retained by an end disk 36 upon the said shaft while a helical projection spring 37 encircles the said shaft and engages the slide plate. The arm 30 being tubular is provided with a perforation 38 in the side thereof substantially opposite the lever 29 and is of suliicient diameter to readily receive the locking pin shaft disk 36 when such perforation is positioned in alinement with the locking pin. When the post is seated upon the shackle hooks as illustrated in Fig. 8, the said hooks are received Within the head notches 20 and at the same time have their terminal ends 39 slidably positioned in the opposite sides of the slot 22 so that the nut 21 may be moved upon the threads of the shank 17 to engage the hooks 19 with their ends 39 fitting within the nut and being positioned within the said slot.

From this detailed description of the device, it will bereadily seen that the shackle 'is easily attached and detached from the locking post by means of the lock nut 21 so that the shackle itself is readily opened as shown in Fig. 11 for the insertion of a staple hasp or any other desired member and is then readily closed as'illustrated in Fig. 8 by applying the locking post and mounting the lock nut upon the threaded shank thereof. lVhen the shank and post are assembled as shown in Fig. 8, the lever arm will be positioned as shown in Fig. 6 and with its perforation 38 out of registry with the looking pin disk so that the said disk will be resiliently held against the closed side of the arm, it being noted that the plate 35 is secured within an enlarged portion d0 of the bore 27 by means of the said arm 30 while the locking pin shank may he slidably moved therethrough when the perforation 38 is positioned in alinement with the pin shaft as illustrated in Fig. 7 and which latter positioning of the arm is effected by turning the lever to its dotted line releasing position as shown in Fig. 2.

It will thus be seen that a keyless lock is provided in which the closed shackle is readily positioned within the casing when the operating lever isin its released position and is automatically retained therein by the spring pressed locking pin 33 being projected through the neck opening 28 while the pin is readily depressed for releasing the shackle at any time when the lever is so positioned although upon shifting the lever to any other position when the pin is projected, the arm perforation will be brought out of alinement with the pin shaft and the pin will be thus prevented from longitudinal movement and will thereby lock the shackle within the casing. The opening and closing of the shackle is also apparent from the above description being possible after the shackle and post have been thus released from the casing so that the mere releasing of the shackle from the casing does not entirely effect a releaseof-the shackle from the members which are positioned therein and secured thereby.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, itis nevertheless to be understood that minor changes may be made in the form, proportion and details of construction Without departing from the spirit and scope of the invention as set forth in the appended claims.

What I claim as new is "l. A device of the class described comprising a cup-shaped casing having a slot ted neck provided with a perforation in one side thereof, a post removably positioned within the said neck, automatic locking means upon the said post, releasing mechanism for the said locking means and a shackle removably secured to said post.
